One of the better explanations I have heard about how God knows what will happen about everything even though we have free will to do as we please is this...think of God's omnipresence as someone who is watching overhead a scene like this: someone is driving a car down a roadway and minding thier own business living their life with nothing in sight for miles, clear sailing as it were. Somewhere else, coming from another direction entirely is someone else driving another car with the same carefree situation. Now here is God because He sitting up above having the perspective to see all situations at the exact same time can look ahead to what is about to happen next. What happens next is these two lives intersect in a car accident from these two individuals not paying attention. God knew this because He had the perspective to see what was about to happen. I know this isn't a good example of how His will works together for the good but just gives a glimpse of an explanation to see how His omnipresense might work. We just don't have the perspective or knowledge that our God has - we don't know it all. As far as His will working together for good just look to the scriptures for that explanation. Romans 8:28 "and we know that in all things God works for the good of those who love him, who have been called according to his purpose" We are all sinners that have fallen short of the grace of God and deserve death. That is why Jesus came so that we could have eternal life even though we don't deserve it. His blood covers our sin. He was the unblemished lamb that provided not only the death that sin requires but the reconcilian to God that we needed because He was sinless. That is what gets us the reconciliation part - the fact that He was sinless and perfect and He had no reason to die. Because we have free will, God doesn't override our choices that we make, but He works through miracles and through all believers (and sometimes non-believers) with prayer and messages through the Holy Spirit. Which if we are listening can result in God's will being acomplished through us despite the bad situations that come up. God can make anything happen - He is God. He seems to choose to let us make our own choices and work through those that love Him so His will can be accomplished though us. That is why it is so important for a Christian to always seek God in every situation so that we don't do things the hard way when God knows the best way. --that's just my opinion--
